Configure server migration in a cluster

Before you begin

Ensure that you have created a machine and have assigned Managed Servers to it. For more information on configuring a machine, see Create and configure machines. For more information on assigning servers to a machine, see Assign server instances to machines.

Ensure that you have configured Node Manager and that you have enabled automatic migration for at least one clustered server. For more information, see Administering Node Manager for Oracle WebLogic Server.

Also ensure that you have configured a data source that can be used by each migratable server to restore session data after being restarted on another machine. You must configure each migratable server in the cluster with this data source. For more information on configuring a data source, see Configure JDBC generic data sources.

To configure server migration in a cluster:

  1. In the left pane of the Console, select Environment > Clusters.

    The Summary of Clusters table displays all the clusters defined in the domain.

  2. In the Clusters table, select the cluster for which you want to configure migration.
  3. Select Configuration > Migration.
    1. Under Candidate Machines for Migratable Servers, in Available, select the machine to which to allow migration and click the right arrow. Repeat this step for each machine until all desired machines for migration appear in Chosen.
    2. In Data Source for Automatic Migration, select the data source to be used for automatic migration or click New to create a new data source.
    3. Optionally, define additional migration settings for this cluster.
  4. Click Save.
